Although the high cost of LED lighting is still the key to promote

In Expo Park in Shanghai, the large-scale application of semiconductor lighting has become another important interpretation of Low Carbon Expo ". As in 1867 the French Paris World Expo, 1873 Vienna World Expo tower lights gas lamp, incandescent lamp in 1878 France Paris World Expo, Shanghai semiconductor lighting Expo in the realization of the lighting function at the same time, but also become an important showcase project, and enhance the night Expo artistic expression on the whole.

For the first time in the city streets large-scale use

In recent years, semiconductor lighting has gradually become the focus of competition the new field of energy saving technology. As early as 2000 in Hannover, Germany, World Expo and Japan in 2005, Aichi, World Expo has been part of the use of semiconductor lighting technology, but its application is limited and the scope is very limited.

2010 Shanghai World Expo, LED chip in the indoor and outdoor lighting and landscape decoration, showing each card, displays and other information of the Expo Park in Shanghai.

As "one axis and four Pavilions" as an example, LED is the main way of lighting.

Expo Theme Pavilion in the lighting design using a water curtain projection, solar and semiconductor lighting, combined with lighting control technology to achieve the theme pavilion lighting and environment interaction. Theme museum building landscape lighting using LED technology. In the north and south facades, aluminum curtain wall out of the hollow hole spacing to square gradually decreasing, the formation of facade texture, lighting design by opening in the bottom plate, placed full-color LED light projection line, a sense of rhythm of space optical elevation. The ecological greening wall of the East and the west is decorated with random arrangement of full-color LED decorative lamps, which reflects the interaction between the Expo and nature.

Appearance as "flying saucer" Expo Cultural Center, more use of the lighting with the intention of architectural design concept, highlight the "space visitors" sense of the future, focusing on the investment performance of "light shell saucer" smooth sleek, with round window open and in the surface of the shell ring within the gallery through lighting effect and create a sporadic era vigor on Pujiang side of the landmark image. The lighting is mainly through the side wall of light illuminate the window in the lower part of the installation of LED linear circular window and wall, resulting in the light transmission effect. The shell rises outward from the middle, also placed in the ground by LED light to light up.

Lighting Design Expo Center LED is the main light source. Its interior a 2000 square meters, can accommodate up to 600 people in the middle of the conference hall all use LED lighting, to achieve the green lighting technology from the landscape to the practical leap. The Expo Center of the building exterior lighting also uses two types of color temperature linear LED, for internal lighting. Through intelligent control technology, the building facade presents a rich and efficient night lighting effect.

Chinese Museum concern, the main structure in the appearance of lighting using high color LED light red light, the full performance of the museum "China red" color.

Deputy director of the Shanghai Municipal Economic and Information Technology Commission Zhou Minhao said in an interview with reporters, there are a total of 1 billion 30 million LED chips are used in the Expo Park Expo venues; indoor lighting, by about 80% LED green light, compared to ordinary incandescent lamp energy saving about 90%.

"This is the LED lighting for the first time in the China city block focused on large-scale use, semiconductor lighting technology demonstration application is the world's most concentrated. Zhou Minhao said.

High cost is still the key to the promotion of

"LED lighting in the people at home can be used, but now the biggest problem is that the cost is high, compared with the general energy-saving lamps expensive, may or will be used in the decoration. Zhou Minhao introduction, the current lighting, the government is still to promote energy-saving lamps. 2008, 2009 years, Shanghai City, a total of energy-saving lamps to promote the only 10 million. The promotion of the main energy-saving lamps are simple, such as supermarkets to sell energy-saving lamps, relatively simple in the production. In order to solve the problem of energy-saving lamps, the government will give some subsidies in the promotion process.

Zhou Minhao said, energy-saving effect of simple type energy-saving lamps are equally impressive, if all of the use of 10 million lamps, the annual saving 500 million kwh.

Shanghai semiconductor lighting industry incubator chairman Li Manping believes that World Expo provided a lot of material and data for the study of color LED. These are expected to promote LED lighting into the field of home lighting.
